One More Quick, Dumb Thing To Lower My Words-Per-Post Average

(This fulfills the promise made last week, when I asked “Aquaman or Thequaman”, although in slightly different wording from what I promised then, as I had thoughts during the editing process. Please come back next week while I ask whether having a retrospective means the first time we encounter a thing is its trospective, or whether planning the thing out would be our pretrospective.)
